This coin always confusing me, is this small or large date please? and do you see any doubling on the "S"? thank you
Nice pictures, but unfortunately it is a large date. That tail on the 9 is a dead giveaway. See http://lincolncentresource.com/smalldates/1970Ssmalldate.html
The mint mark of the "S" during those 68S-72S years were worn and "bloby" to begin with. The 70S does have some RPMs , but yours is standard, Jim
